Great choice!
Recently received the GLA GRO Paintball Regulator. This option is the perfect choice to provide flexibility. It comes with everything needed to connect to the large disposable cartridges, paintball tanks, and large full size tanks. The regulator feels so well made and is working perfectly. Appreciated all the help from GLA to understand the options and help me make the right choice for me.

Beautiful Co2 regulator, and then some.
To my surprise this regulator comes out of the box with all necessary adapters to fit every co2 cylinder. I purchased a few disposable cylinders for emergencies just in case. Amazing quality and the finish is well done. I ohm tested the surface just to check and it’s on par with our aircraft parts here at my job. This is good quality equipment at a very affordable price.

Stellar paintball regulator
Very well made co2 regulator that delivers precision co2 and stability through the life of the cylinder gas contents. Couldn't be more pleased.
-
GLA all the way baby!
I have other GLA regulaotrs but this is my first paintball. Its GLA quality all the way and what you would expect. GLA is the best in co2 no doubt about it. Built in solenoid, and comes with all the adapters for ll the various cylinder types.

The Gro co2 regulator is the most versatile regulator I’ve ever owned.
Last week I bought the HLA paintball adapter for my Gro regulator I used for disposable cartridges. I must say, this is one terrific co2 regulator. The solenoid is built in with the needle valve on the adjacent side. The needle valves precision is extremely accurate and makes adjusting super easy. I like that I can either go back to a cartridge cylinder or even a full sized cylinder using their OEM adapters. It’s always steady in my settings and I’ve never had a compliant. Good products backed by even better people at GLA.

Great build quality compared to Fzone
This is much higher end than the Fzone and other generic brands. Super precise in its bubble flow rate adjustments, much easier and stays rock solid everyday. One thing I noticed in the box is they give you the CGA-320 adapter as well with this regulator. Therefore out of the box this thing is adorable to every cylinder type, even their disposable cylinders. Can’t beat this.
-
I love this regulator.
Extremely pleased with GLA and this regulator. Very fast dispatch service and quality product. My aquarium is happy and already on my second refill after 4 months. Installation was very easy and getting co2 up to snuff was very smooth. I’d buy another one if I needed.

Great quality
Using this on a 5lb. tank in it is working perfect. I am getting a consistent bubble rate and pressure is holding right at 35psi. Turning on and off with no issues. Extremely happy with my purchase and the rock solid quality and very competitive price.
-
Quality and support
I went with the lower priced regulators from Amazon thinking they were good enough. They don’t have psi adjustment so I thought I had a defective unit. David from GLA got me up to speed. Bubble count is solid, unlike the cheaper units. I’ll be replacing my other regulators with GLA!

A Superior Product - The Best Paintball CO2 Regulator
This is quite simply the highest quality paintball regulator on the market. I had recently returned an FZONE brand regulator, which was both extremely low quality in many areas and impossible to get an air-tight seal. Immediately I saw how much better GLA's product was in all areas. The installation directions were easy to read and better than anything else I've seen in the hobby.
